I think if she had time, she would do it in a painless way, i.e., poison or suffocating him in his sleep. But, I do think that if need be, she could stab him if she didn't have the time to slowly and painlessly kill him.

Oh, I see! I am not sure what he would do to distract himself. I guess if he truly lost and it was over, maybe he would just find some building project to devout himself to. I don't think Morgause would care as long as she is able to still mess with him when she wants to.

I am not sure if Artos would end his life. I just think of him as too much of a passive character but I guess if it came down to it. He could. I think he would have to be wounded a bit. I don't think he would give up without a fight though, in some sense, he has to fight and lose for him to think about ending his own life. I don't know if he could kill Lleu. Even if he knew Morgause would take him. I don't think he would do that. I don't know why but he is just not a character I can see killing his own son, even if it was out of love or concern for him.

But if he had to, I think he would have someone else take care of it. They would have to go about it so Lleu doesn't see it coming, i.e., poison, killing him in his sleep, or stabbing him in the back.

I think if Morgause has Artos she will still desire Medraut. She has her claws in him, she has power and authority of over Medraut in a way she will never have over Artos. Medraut will never truly be her equal and she likes that.

I don't know if jealousy is the right word for what I imagine Artos would feel in that situation. In some sense, disgust with a twinge of jealousy but also regret and maybe shame? He would be jealous because I do still think he has feelings for Morgause and a lot of his mistakes are borne out of those feelings. But he would also be disgusted at Morgause and what she is doing with her own child. A part of him would also know that it was his fault as well. He in some way did allow this to happen. He knew Morgause and who she had become and he knowingly sent his child to live with her.

Again, I do not think that Artos is jealous of Lleu and Medraut. Maybe his is jealous of their intimacy, their closeness but not their relationship. He does not want to see Lleu and Medraut pretty much reenact his own mistakes. Although, I do have to say that I think Artos and Morgause's relationship is different than Medraut and Lleu's. Theirs started more innocently in my mind even if it is the reason everyone else suffers.

Hmm, I am not sure. I haven't thought too much about Morgause and Artos's relationship. I do like to think that it was, at least at the start, very different from any other of their relationships. Their relationship was at first built on genuine affection and love for the other person but it of course soured and they ended up hurting and betraying each other. The turn their relationship takes ultimately leads to everyone else's suffering. I like to think betrayal and manipulation was something Morgause learned as her and Artos's relationship dissolved and rotted.

Forget about everything else I wanna see the of OG sibcest, headcanon that Morgause was older than Artos and had to baby him in the same way Goewin and Medraut had to with Lleu which is why she feels as if Artos owes her something.

I'd kill for a prequel or a short story about Artos and Morgause. They give off proto Medlleu vibes (legitimate child/bastard, healer poisoner/swordsman, jealousy, incest). I find it curious that Morgause had Artos in a vulnerable position and chose to seduce him instead of using this opportunity to murder him right then and there. If she had only wanted the crown she could have picked the easier way. Contrary to all reason she tried to babytrap her brother and thought he would make his sister queen when presented with their bastard. This plan never would have worked if Artos had never felt more than physical attraction towards Morgause.

Furthermore Morgause never seriously tried to murder Lleu in TWP and Artos never really punished her for poisoning his most treasured child which implies there exists still some sort of affection between them (or that she still has some sort of sway over him). He was harsher on Medraut than Morgause. Maybe Artos wasn't mad that Morgause fucked Medraut, because she violated his son but he was jealous that she was fucking his son and not him. He is unable to love Medraut. To him it must be like seeing a corrupted version of himself. Morgause used Medraut as a canvas to carve the psychological trauma she inflicted onto Artos and he tried to conceal from the eyes of others, in physical form into Medraut for all the world to see. Medraut's existence will always be a reminder of the sins Artos had committed and a knife to rip open old wounds. In no Human Hands to Touch Morgause herself says making Medraut her lover was a way to triumph over her brother. I could imagine that Morgause had been projecting Artos on him while Artos had been projecting Morgause on him. Medraut had been hurt and molded by them, because his parents could not punish and change the person they felt betrayed by.

It's quite ironic that the child that Artos favoured ends up to be the most like his sister. Perhaps this is the true reason why Artos loves Lleu so much. At least subconsciously he must have picked up on their similarities.

My headcanon, just like yours, is that Morgause is the elder sister and Artos the little brother. In Camelot 2011 Morgan accuses Uther of having murdered her mother, which made it possible for him to marry Arthur's mother Igraine. I like your idea that as a child Morgause was longing for Igraine's love, even though her stepmother was also the reason of her mother's death. I could imagine that Morgause tried to harm Artos when he was a baby, as a form of revenge for her mother (she couldn't kill Igraine because she liked Igraine and felt like it was Igraine's duty to replace her mother and love her like her own child as rependence for her marriage with Uther), but then baby Artos grabbed her ring finger with his tiny hand which held the knife and she was stunned as she was met with the full force of Artos' gaze. Artos' first sight would be filled with the image of his sister. And then she decided that Artos was hers <3

I'm fond of Lleu-Morgause parallels. They are both legitimate children with a claim to the throne, they are prideful, vain and cruel. They have a liking for luxury goods and exotic pets, in particular birds. I imagine that they both felt trapped and powerless during their childhood. Lleu by his illness and his father's protectiveness and Morgause felt shackled by her gender and the strict rules of the convent she was send to. In the beginning she might have assisted Artos in his quests and lived vigorously through him.
